Abstract

In Armenia the mountainous natural hayfields are the best fodder base for cattle breeding. However they are covered with superficial and slim stones, straw, bushes, located on curve surfaces and in that conditions the operational results of feed harvest machines are low. In mountainous hayfields based on КС-2.1 grass mowing machine statistical data results were created their uninterrupted work duration probability density's statistical diagram, reliability's, statistical and probable function's modification graphs. The durability's dispersal hysteresis of eliminating failures, statistical and theoretical functions' modification graphs. The analysis result of researches shows that the operational reliability of grass mowing machine is very low. The results are shown in table. The failures' reasons are clarified. The goal is to raise the grass mowing machine operational reliability with two ways simultaneously – to improve the landscape surface areas and make durability calculation for finger and finger beam and process rational methods of repairing them for raising their firmness.

山地草场割草机的运行可靠性及其饲养方法
在亚美尼亚,山地天然草场是最好的养牛饲料基地。然而,它们被表面和细长的石头,稻草,灌木覆盖,位于曲线表面,在这种条件下,饲料收获机的操作结果很低。基于КС-2.1割草机统计数据,绘制了山地草场割草机不间断工作时长概率密度统计图、可靠性统计图、概率函数修正图。耐久性消失后的扩散迟滞、统计及理论函数修正图。研究分析结果表明,除草机的运行可靠性很低。结果如表所示。阐明了失败的原因。目的是同时从提高景观表面积和手指、手指梁耐久性计算两方面提高割草机的运行可靠性,并对其进行合理的修复,以提高其牢固性。
